Was fine but had recall N23 done which knocked it out. They came out with an update and had it reflashed - it worked (no light and lorange worked) from Nov 2014 until Aug 2015. Now the Service 4wd is light is constantly on, no lo range - again.

Service 4WD System light would occassionally turn on for a few days then go away. First 2 mechanics could not find problem, 3rd mechanic changed wheel sensors, stayed off about 9 months now comes on when I start car but goes away after a few seconds.

Servive4wd message. No 4 wheel lo after n23 flash. No steady message either. After p73 flash problem fixed for about a week. Now Service 4wd message on 95% of the time as well as check engine light. No 4 wheel drive lo working

Service 4wd system light comes on when trying to select lo range only. Lo range will not engage, dealer can't find anything wrong. Reset and worked that weekend then started same problem the next day. Dealer still finds nothing wrong.
